Easy Appointments uses tables prefixed wp_ea_appointments, wp_ea_services, wp_ea_workers, wp_ea_locations, and wp_ea_connections. The connections table is the heart of the plugin: it links a service, worker, and location and defines an available time window. Appointments reference those entities through foreign keys.

The default admin gives a list of appointments and a calendar. To answer a question like "which workers handle the colour service at the Berlin location next week", an admin opens the connections page, the workers page, and the appointments list in three tabs. The default columns surface only IDs and labels, and bulk approval or rejection isn't a first-class workflow.

SleekView reads wp_ea_appointments directly and joins to wp_ea_services, wp_ea_workers, and wp_ea_locations by ID. Status, customer email, and notes become inline-editable columns, connection details appear as joined fields, and saved views replace the three-tab dance with a single filterable grid.

Easy Appointments models the world well: services, workers, locations, and the connections that allow a service to be performed by a particular worker at a particular location. The plugin's data model captures that complexity, and its calendar visualises one slice of it at a time. The cost of single-slice views is operational.

A practice owner who runs three locations and seven workers wants to see today's appointments across the whole practice, not three separate calendars. A worker wants their own day sorted by time, with location and service inline. A reception lead wants the pending-approvals queue across locations so nothing slips.

SleekView reads the same tables Easy Appointments writes, joins them once, and turns the model into a single editable grid. Approving an appointment inline still fires the plugin's notification hooks. Connections, locations, and services join cleanly because they're already related in the schema.

The reporting question stops being a SQL exercise and starts being a saved filter.
